Grant: COM7 moved to UHF 55 as part of the clearance, however it will be closing on 30th June when it's licence expires, so don't waste any time or effort on it. COM8 closed nearly two years ago, both were only ever intended to be temporary .

Has Quest been removed from the EPG? Service became at some point today earlier and, on retuning, 12 has disappeared entirely.

David:

Quest has not been removed and is still broadcasting.
It is never advised to retune if you were correctly tuned and having difficulties. Retuning will never fix a reception problem. If you retune when you have or pixelllated pictures it usually just clears your correct tuning. You will no doubt find that you are also missing other on the same (SDN/COM4).

Your problems with reception were most likely due to current weather conditions causing some "Tropospheric Ducting" resulting in coming from distant transmitters (in Europe or the UK) which is currently affecting some parts of the of the UK.

You will need to retune again when your signals are normal. As you don't know when that will be, you may have to try several times.

David: Quest recently moved to the COM6 (it was previously on COM4), so try a manual tune on UHF 35.

David Nixon : The BBC website [bbc.co.uk/reception] is not showing any faults for the .

The HD are on the PSB3 (BBC B) , which is on UHF 28 from Darvel, and you should try a manual of this channel.
